Believe it or not, the existence of altcoins is why this space is crowdy today, many people cares only about altcoins and it favours them, the difference is we can never know how smart and strong the team of a new project is, either its going to fail or survive is hard to know, but still, the future builds are only possible on altcoins right now. Its a fact that I have learned to accept.
I agree with you, I believe that without altcoins, the cryptocurrency industry would not be able to grow big and attract new investors every year. If you conduct a survey of new investors. I believe up to 90% of them entered this market because they were attracted by the x100, x1000 growth of meme projects, shitcoins being created, Bitcoin was never on their radar.
This is true and what is happening, but maximalist bitcoin investors are trying to deny this and they claim that it is bitcoin that attracts new investors, while altcoins are ruining reputation of the cryptocurrency industry.
As of now, my portfolio is over 70% bitcoin but I don't want to lie that investing in altcoins is bad, it's not as bad as many people are saying.
